FIELD OF THE INVENTION

The present disclosure relates generally to an electronic payment service or system, and more particularly to an electronic payment service or system that allows a secure payment to be made to a participating merchant interactive voice response system.

BACKGROUND OF THE INVENTION

An interactive voice response system, which is sometimes referred to as a Call Tree, includes both hardware and a software application that accepts a combination of voice telephone input and/or touch-tone keypad selection and provides appropriate responses. An interactive voice response system is usually a part of a larger application that includes database access.

Merchant interactive voice response systems are generally not designed to handle secure electronic payments without the intervention of a human, who actually takes the order and queries the caller for payment or credit card information. Customers commonly issue authorizations to merchants over the telephone, but the process is relatively slow, cumbersome and relatively expensive due to the cost of live customer service employees and the amount of information involved. The customer service employees typically prompt customers for many pieces of information such as credit card numbers, expiration dates, security code, name on the credit card, credit card billing address, telephone number, etc. The obtained information must then be manually entered into a computer system, thereby contributing to the slowness and expense of the process.

SUMMARY OF THE DISCLOSURE

The present disclosure relates to a method, system, and computer readable medium for providing secure payments. An interactive voice response (IVR) system under the control of a merchant receives calls from at least one customer having a communications device. The merchant's interactive voice response system requests a payment from the customer, and the customer responds to the request by providing authentication information and payment amounts for a payment service. The payment service provides the customer with a token having a payment service ID number and a one time use transaction ID number. The customer provides the token information to the merchant's interactive voice response system which transmits the token information back to the payment service. The payment service issues an electronic payment or payment information to the merchant upon validation of the token information.

FIG. 1A shows a block diagram for a secure payment system 100 of the present invention. The system 100 includes a merchant interactive voice response system 101 that a caller may access through the PSTN or VoIP network 102. Preferably, the user accesses the interactive voice response system 101 with a wireless device 103 or some other intelligent communications device (wireless or wired) that includes a software module such as an applet configured for use with the secure payment system 100. Both the interactive voice response system 101 and the wireless device 103 have access to a data network 104, such as the Internet, and the data network 104 provides the interactive voice response system 101 and wireless device 103 with access to a service provider/payment provider 105 and its partners 106-108. The service provider/payment service 105 may be an organization such as AT&T®, and the partners 106-108 could include companies such as VISA®, Mastercard®, Paypal® and Verisign®. In another embodiment, service provider 105 may not exist as a separate entity independent of partners 106, 107 and 108. In other words, partners 106, 107 and 108 may perform the functions of the service provider 105, may be directly connected to the data network 104 and may communicate directly with the merchant interactive voice response system 101 and wireless device 103. An applet is used herein to demonstrate an embodiment of a software module that may reside on device 103, but any suitable software module type may be used. It should be noted, that, if an independent service provider 105 is not included in the overall system of FIG. 1A, the target partners 106, 107 or 108 may be uniquely identified using any combinations of physical keys, soft keys and menus.

In order to utilize and participate in the secure payment system 100, the caller or customer must first have or download an applet on to the wireless device 103 or intelligent communications device. The applet is preferably password protected or protected by a biometric information input device, in case the wireless device 103 is lost or stolen. The user may also store payment information, such as credit card information or bank information, in order to avoid the repetitious entry of data and to enhance the rapid transfer of financial information to the system.

FIG. 1B shows the interactive voice response system 101, communications device 103 and payment service 105 in more detail. The interactive voice response system 101 which is under the control of a merchant includes a call receiver module 111 for receiving calls from at least one customer having a communications device 103. The merchant's interactive voice response service system 101 requests a payment from the customer, and the customer responds by providing authentication information and payment amounts to the payment service 105 from an authorization and payment amount module 112. In order to transmit the authorization and payment amounts, secure sessions modules 117, 118 are utilized to setup a secure session between the communications device 103 and the payment service 105. The payment service 105 provides the customer's communications device 103 with a token having a payment service ID number token and a one time use transaction ID number token. The payment service ID number is provided by a payment service ID number module 113, and the one time use ID token number is provided by a one time use ID token number module 114. The customer's communications device 103 provides the token information to the merchant's interactive voice response system 101 which transmits the token information back to the payment service 105 utilizing secure session module 116. The payment service 105 issues an electronic payment or payment information to the merchant from an electronic payment and authorization module 115, upon validating the token information.

FIG. 2 shows an activity diagram for the secure payment system 100 and the merchant interactive voice response system 101 of FIGS. 1A and 1B. After the customer has had the relatively simple applet installed on his wireless device 103, and after the customer has entered the appropriate identification data and payment information for the first time, the customer is ready to place a telephone call to the merchant system 101 as indicated in step #1. As mentioned above, the preferred wireless device 103 is a data capable cell phone, but any wired or wireless intelligent communications device can be utilized, including a personal computer, PDA, Internet appliance, video game console, television set top box, etc. The call of step #1 links the caller's device 103 to the merchant interactive voice response system 101 and allows the customer to interact with the merchant's interactive voice response system 101 using key presses and DTMF signaling as is customary in the art.

After the customer has indicated to the merchant interactive voice response system 101 that the customer wants to purchase the merchant's products or services, the interactive voice response system 101 requests payment information from the caller's device 103 in step #2. The interactive voice response system 101 also indicates to the customer that it will accept a secure payment from the customer using the service provider's payment service 105. In response to the request for payment information, the customer in step #3 presses a payment key on his wireless device 103. The payment key may be a dedicated key labeled “PAY”, a softkey or even one of the keys present on a conventional keypad. At this point, the applet on the wireless device 103 prompts the user to enter a password or PIN. Alternatively, the customer can be prompted to provide biometric information such as identity authentication information via a finger printer reader, a voice recognition device or an iris recognition device. The identify authentication information can be converted into a PIN. The applet also prompts the customer to enter a monetary amount, which can be entered via a keyboard or a voice input. Lastly, the applet provides the communications address, i.e., in this embodiment the telephone number of the interactive voice response system 101 (which is extracted from the current call), the PIN and the monetary amount to the payment service 105 via a secure session (for example, SSL) over the data network 104.

In step #4, the payment service 105 validates the PIN, and responds with a numeric token containing a payment service ID number and a one-time use transaction ID number. The numeric token is communicated back to the wireless device 103 via the data network 104. In step #5, the wireless device 103 plays out the numeric token to the merchant interactive voice response system 101 using DTMF signaling in the original voice call set up over the PSTN or VoIP network 102. In response to the DTMF signals provided by the wireless device 103, the interactive voice response system 101 in step #6 looks up the URL for the payment service 105 based on the payment service ID provided, and the interactive voice response system 101 establishes a secure session (for example, SSL) to the payment service 105 via the data network 104. The interactive voice response system 101 also provides the payment service 105 with the one-time use transaction ID. Reference is made to numeric IDs and tokens in this document to illustrate particular implementations using digits only. But, the same mechanism can be utilized with various alphanumeric encodings and alphanumeric tokens.

In step #7, the payment service verifies that the merchant interactive voice response system 101 requesting payment corresponds to the telephone number provided in the initial request. Such a request avoids issues in which the transaction ID may have been compromised on the PSTN or VoIP connection. The payment service 105 validates the one time use transaction ID, and either issues an electronic payment or provides the appropriate credentials (for example, credit card information, address etc. to the merchant interactive voice response system 101). Lastly, in step #8 the interactive voice response system 101 announces to the customer that payment has been received from the payment service 105.

FIG. 3 shows an illustrative embodiment of a general computer system, on which secure payment system 100 can be implemented and is designated 300. The secure payment system 100 is preferably implemented using a plurality of computers 300.

In a particular embodiment, the computer system 300 can be implemented using electronic devices that provide voice, video or data communication. Further, while a single computer system 300 is illustrated, the term “system” shall also be taken to include any collection of systems or sub-systems that individually or jointly execute a set, or multiple sets, of instructions to perform one or more computer functions.

In a particular embodiment, as depicted in FIG. 3, a disk drive unit 380 may include a computer-readable medium 382 in which one or more sets of instructions 384, e.g. software, can be embedded. Further, the instructions 384 may embody one or more of the methods or logic as described herein. In a particular embodiment, the instructions 384 may reside completely, or at least partially, within the main memory 320, the static memory 330, and/or within the processor 310 during execution by the computer system 300. The main memory 320 and the processor 310 also may include computer-readable media.

In an alternative embodiment, dedicated hardware implementations, such as application specific integrated circuits, programmable logic arrays and other hardware devices, can be constructed to implement one or more of the methods described herein. Applications that may include the apparatus and systems of various embodiments can broadly include a variety of electronic and computer systems. One or more embodiments described herein may implement functions using two or more specific interconnected hardware modules or devices with related control and data signals that can be communicated between and through the modules, or as portions of an application-specific integrated circuit. Accordingly, the present system encompasses software, firmware, and hardware implementations.

In accordance with various embodiments of the present disclosure, the methods described herein may be implemented by software programs executable by a computer system. Further, in an exemplary, non-limited embodiment, implementations can include distributed processing, component/object distributed processing, and parallel processing. Alternatively, virtual computer system processing can be constructed to implement one or more of the methods or functionality as described herein.

The present disclosure contemplates a computer-readable medium 382 that includes instructions 384 or receives and executes instructions 384 responsive to a propagated signal, so that a device connected to a network 301 can communicate voice, video or data over the network 301. Further, the instructions 384 may be transmitted or received over the network 301 via the network interface device 340.

While the computer-readable medium is shown to be a single medium, the term “computer-readable medium” includes a single medium or multiple media, such as a centralized or distributed database, and/or associated caches and servers that store one or more sets of instructions. The term “computer-readable medium” shall also include any medium that is capable of storing, encoding or carrying a set of instructions for execution by a processor or that cause a computer system to perform any one or more of the methods or operations disclosed herein.

In a particular non-limiting, exemplary embodiment, the computer-readable medium can include a solid-state memory such as a memory card or other package that houses one or more non-volatile read-only memories. Further, the computer-readable medium can be a random access memory or other volatile re-writable memory. Additionally, the computer-readable medium can include a magneto-optical or optical medium, such as a disk or tapes or other storage device to capture carrier wave signals such as a signal communicated over a transmission medium.

Accordingly, the disclosure is considered to include any one or more of a computer-readable medium or a distribution medium and other equivalents and successor media, in which data or instructions may be stored.

There are several advantages that the secure electronic payment system provides over conventional systems. For example, the secure electronic payment system reduces a merchant's operational costs by allowing payments to be processed without involving a customer service representative. The system encourages customers to make payments by phone, since the customer only has to make a few key-presses, and the process takes less time than to talking to a live customer service representative. The system can be added relatively easily to a communications company's existing infrastructure without substantial modification of the existing infrastructure. Lastly, the system can be implemented with a high level of security through the use of secure data sessions (for example, SSL), PIN based or biometric based authentication, one time use transaction ID's, and validation of the mapping of an interactive voice response called number to the actual merchant requesting payment.

Although the present specification describes components and functions that may be implemented in particular embodiments with reference to particular standards and protocols, the invention is not limited to such standards and protocols. For example, standards for Internet and other packet switched network transmission (e.g., TCP/IP, UDP/IP, HTML, HTTP) represent examples of the state of the art. Such standards are periodically superseded by faster or more efficient equivalents having essentially the same functions. Accordingly, replacement standards and protocols having the same or similar functions as those disclosed herein are considered equivalents thereof.
